Description
- General description: β-galactosidase is a 465 kDa tetrameric protein.[1] It is coded by the LacZ gene.[2]
- Application: β-Galactosidase from Escherichia coli has been used to produce biocatalytic Ca-alginate beads on a B-390 encapsulator (BUCHI).[3] It has been used to prepare the source droplet solution and also as the cargo for Pep-1 (KETWWETWWTEWSQPKKKRKV-cysteamide).[4]
- Biochem/physiol Actions: β-galactosidase cleaves lactose into its monosaccharide components, glucose and galactose. It also catalyses the transglycosylation of glucose into allolactose, the inducer of β-galactosidase, in a feedback loop.
- Packaging: Package size based on protein content
- Physical properties: Tetramer molecular weight 465 kDa (subunits 116.3 kDa each)
- Unit Definition: One unit will hydrolyze 1.0 μmole of o-nitrophenyl β-D-galactopyranoside to o-nitrophenol and D-galactose per min at pH 7.3 at 37 °C.
- Physical form: Stabilized with phosphate buffer and sucrose
